ened. Wings hyaline. Antennae very long and slender, nearly as long as the 



body and gradually attenuated 

 toward the apex; very many 

 jointed, the joints toward the 

 tip short, quadrate, but those 

 near the base considerably 

 elongated, apparently from three 

 to five times as long as thick. 

 Thorax and abdomen only 

 faintly preserved, apparently 

 smooth and shining. Wings 

 hyaline, the stigma and veins 

 dark brown; stigma elongate, 

 but distinctly angled below, the 

 radius originating near its mid- 

 dle. Marginal cell narrow, 

 elongate, acute at the tip; first 

 and second sections of the radius 

 both short, the second fully 

 twice as long as the first ; second 

 cubital cell short, trapezoidal, 

 but little longer than high; 



median and submedian cells of front wing of equal length. 



Fig. 87. — Bracon resurrectus, sp. nov. Type. 



Described from one specimen and reverse, not particularly well 

 preserved, but very striking on account of its large size. Nos. A137- 

 138, collected at Station 14 by Mrs. W. P. Cockerell. 



Rhogadinae. 



The only hitherto described fossil species belonging to this sub- 

 family is Rhogas tertiarius, Brues ('06) from Florissant, but later 

 material from this locality contains the following species of Exothecus. 



EXOTHECUS ABROGATUS, sp. llOV. (Fig. 88.) 



Length 5 mm. Ovipositor 6.5 mm. Black, the abdomen toward the tip 

 and the legs brownish; wings hyaline or very slightly yellowish. Antennae 

 piceous, extremely slender and presumably long, although only the basal 

 part about two-thirds the length of the body is preserved; the joints appear 

 to be elongate, about three times as long as thick. Head and thorax seen in 

 lateral aspect, smooth and shining, the eye very large, round; metathorax 

 finely areolate and propleura very finely rugosopunctate. Abdomen elongate,
